I've been using pentosin, 5-40 fully synthetic. But because I have about 140K miles on my 30v, should I change it to Castrol Syntec 10-30 now?

Why would you want to change? ... the Castrol Syntec 5W40 is an ACEA A3 rated oil that also meets VW 502/505 and the Syntec 10W30 is not.

Boo Castrol.

Mobil, Motul, ... there's lots of good brands out there to choose from.

I use Mobil 1 0W-40, when I get the cash I'm buying a big bulk order of Motul I think.

Brand doesn't concern me as much as viscosity does. After talking to my uncle who used to be a mechanic, he said that due to the wear on the motor, a thicker oil should be used - 10-30. Should I switch?
